본 고안은 기름 보일러용 전자 펌프의 내압 시험기에 관한 것으로, 특히 전자펌프가 규정된 압력에 견디는 가의 여부를 시험할 수 있도록 한 것이다.The present invention relates to an internal pressure tester for an electronic pump for an oil boiler, and in particular, it is possible to test whether the electronic pump can withstand the prescribed pressure.

통상적으로 기름 보일러에 사용되는 전자 펌프는 허용 압력에 견디지 못하게 되면 사고의 요인이 되는데, 현재까지는 이의 허용 압력을 간편히 측정할수 있는 내압측정장치가 없었던 것이다.In general, an electronic pump used in an oil boiler is a cause of an accident when it cannot tolerate the allowable pressure. Until now, there has been no pressure measuring device that can easily measure the allowable pressure.

따라서 본 고안은 상기한 바와 같은 종래의 결점을 감안하여 안출된 것으로서, 특히, 전자부품의 내압시험을 극히 간편하게 할 수 있도록 한 시험기를 제공하려는데 그 목적이 있는 것으로 이하 첨부된 도면에 의거 상세히 설명하면 다음과 같다.Accordingly, the present invention has been made in view of the above-mentioned drawbacks, and in particular, it is an object of the present invention to provide a tester that enables extremely simple withstand voltage test of electronic components. As follows.

일측에 기름탱크(1)와 유압과 공압을 동시에 이용하는 유공압실린더(2)를 장설하되, 유공압실린더(2) 전방에는 유로관(3)을 장설하고, 유로관(2)의 양측 밸브(4) 및 (5)를 그리고 밸브(5)의 외측부로 압력게이지(6)를 장설하며, 밸브(4)와 밸브(5)사이에 밸브(7)를 장설한 기름탱크(1)의 유로관(8)이 연결되게 하였으며, 타측에는 중앙부에 밸브(9)를 장설한 ""형 토출관(1) 및 비이커(11)를 장설하고, 각각의 밸브(4)(5) 및 (7)(9)와 에어유닛트(12)에 타이머(13)가 연결되어 제어할수 있도록 한 기름 보일러용 전자 펌프의 내압 시험기인 것이다.An oil tank (1) and a pneumatic cylinder (2) for simultaneously using hydraulic pressure and pneumatic pressure are installed on one side, and a flow path pipe (3) is installed in front of the hydraulic pneumatic cylinder (2), and both side valves (4) of the flow pipe (2) are installed. And (5) and a pressure gauge (6) installed outside the valve (5), and a flow pipe (8) of the oil tank (1) having a valve (7) installed between the valve (4) and the valve (5). ) And the valve (9) is installed at the center of the other side. &Quot; Type discharge tube 1 and beaker 11 are installed, and timers 13 are connected to the valves 4, 5 and 7, 9 and air unit 12 so as to be controlled. It is an internal pressure tester of an electronic pump for an oil boiler.

미설명 부호14는 배출관, 15는 오일받이 탱크, 16는 전자 펌프이다.Reference numeral 14 denotes an exhaust pipe, 15 an oil sump tank, and 16 an electronic pump.

위와 같이 구성된 본 고안의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above are as follows.

전자펌프(16)에 내압시험을 하고자 할때는 유로관(3)의 단부에 전자펌프(16)의 흡입부를 접속시키고, 전자펌프(16)의 상단에 형성된 토출부에 ""형 토출관(10)의 일단을 접속시킨 다음 전원을 인기시키면 전자 펌프가 가동 되는데, 이 상태에서 밸브(9)와 밸브(5) 그리고 밸브(7)를 개방시켜 기름탱크(1)에 담겨져 있는 기름이 유로관(8)및 전자펌프(16)를 통하여 비이커(11)에 흐르게 하여 이 상태를 10초 정도 유지시킨 다음 밸브(9)와 (7)이 잠겨지게 하고 밸브(4)가 열리게 한 후 유공압 실린더(2)를 동작시켜 압력게이지(6)가 규정된 한후 유공압 실린더(2)를 동작시켜 압력게이지(6)가 규정된 압력이 될때 까지 압력을 높여준 다음 1분간 이 상태를 유지시킴으로서 시험이 완료되게 되는 것인데, 이때 밸브(9)와 (7)를 닫은 상태에서 유공압실린더(2)를 동작시켰을때 전자펌프(16)의 동체 외측으로 기름이 새지않으면 합격품이 되는 것으로서 시험이 완료된 후 유공압 실린더(2)의 동작을 멈추고 밸브(5)를 개방시키면 펌프(16)내에 들어 있던 기름이 밸브(5) 및 배출관(14)을 통하여 오일받이 탱크(15)로 드레인되게 되는 것이며 위와 같은 동작을 전자펌프(16) 내압시험기 마다 동일한 방법으로 작용하면서 시험되게 되는 것이다.When the pressure test is to be performed on the electron pump 16, the suction part of the electron pump 16 is connected to the end of the flow path tube 3, and the discharge portion formed at the upper end of the electron pump 16 is " When one end of the " type discharge tube 10 is connected and the power source is popular, the electromagnetic pump is operated. In this state, the valve 9, the valve 5 and the valve 7 are opened to be contained in the oil tank 1 Allow oil to flow through the flow pipe (8) and the solenoid pump (16) to the beaker (11) to maintain this state for about 10 seconds, then allow the valves (9) and (7) to lock and the valve (4) to open. After operating the pneumatic cylinder (2) and the pressure gauge (6) is specified, the hydraulic pneumatic cylinder (2) is operated to increase the pressure until the pressure gauge (6) to the prescribed pressure and then maintain this state for 1 minute The test is to be completed. If the oil is not leaked to the outside of the fuselage of the solenoid pump 16 when the pneumatic cylinder (2) is operated with the valves (9) and (7) closed, the test is completed. When stopping the operation of the pneumatic cylinder (2) and opening the valve (5) If it is turned on, the oil contained in the pump 16 will be drained to the oil receiving tank 15 through the valve 5 and the discharge pipe 14, and the above operation is performed while operating the same method for each of the pressure testers of the electronic pump 16. It will be.

상술한 바와 같이 본 고안은 전자펌프(16)의 내압시험을 매우 간단하게 할수 있도록 한것으로 툭히 구성인 간단하여 제작이 손쉽고 전자펌프(16)의 내압시험을 매우 정확하게 실시 할수 있는 유용한 고안인 것이다.As described above, the present invention is intended to make the pressure test of the electronic pump 16 very simple, and it is a simple design that is easy to manufacture and is a useful design that can perform the pressure test of the electronic pump 16 very accurately.
